Definitions

  • the invention relates to a method for controlling the feed rollers a cutting mill for crushing the scrap skeleton an upstream thermoforming machine of the type of the main claim and a device for performing of the procedure.
  • the feed rollers work also intermittent, with the switching frequency depending after setting less or equal the number of cycles is Thermoforming machine.
  • the speeds of the rotor and the Feed rollers are coordinated accordingly.
  • the invention has for its object the method for Controlling the feed rollers according to claim 1 in a cutting mill Execute according to claim 11 so that a dust and Splinter formation is largely avoided and the susceptibility to malfunction the cutting mill is thus lowered.
  • the characteristic features of the main claim proposed. Through the continuous Operation of the feed rollers eliminates the acceleration and deceleration phases of the feed rollers and dust and Splinters occur to a much lesser extent. Starting from This finding was the object of the invention of further in determining and adjusting the speed the feed rollers in a simple manner.
  • the controller should independently determine the speed based on the size of the intermediate loop, so that changes in the Number of cycles of the upstream thermoforming machine automatically recognized and an adjustment of the speed of the feed rollers can be used.
  • the cutting mill consists of a stator 1 and a stator 1 therein arranged rotor 2, with several knives 3 on rotor 2 are arranged all around, with fixed knives 4 on the stator 1 interact.
  • the stator 1 has an underside Sieve 5 with openings 6, the diameter of which is desired Grist size corresponds. Via a side Pipe connection 7 is the ground material that has fallen through the sieve 5 is sucked off.
  • a slot 8 Through a slot 8, the one upstream and not shown thermoforming machine supplied residual grid 9 from feed rollers 26, 27 of the cutting device fed. Both feed rollers 26, 27 are pressed together and are rotated by a drive 10 transferred.
  • the rotor 2 is driven by a drive 11.
  • the roller 15 is rotatably seated in two tabs 19 with one Shaft 20 are connected.
  • the shaft can be rotated in bearings 21 stored.
  • the rotatable part of a sits on the shaft 20
  • Sensor 22 the rigid part of which is attached to the housing 17.
  • the sensor 22 is designed so that it the angular position of the Swing arm 16 continuously, digital or analog, record and on a controller 23 can report.
  • This control 23 stands with the drive motor 10 for the feed rollers 26, 27 in the Way in connection that its speed is infinitely variable can change by z.
  • B. a frequency converter 24th controls which affects the drive 10.
  • the procedure is as follows.
  • the thermoforming machine intermittently provides a section of the skeleton 9 through a fast-moving feed step associated transport device, whereby the rocker 16th falls down and its lower end position 28 (see diagram Figure 4) reached.
  • the feed rollers 26, 27 push that Residual mesh 9 through the slot 8 and the residual mesh 9 cut off in strips.
  • the rocker 16 has its uppermost layer 29 in the thermoforming machine reached.
  • Another transport step of the thermoforming machine follows and the rocker 16 falls into its lower position 28 'and is brought back into the upper layer 29 '.
  • the controller now recognizes whether the lower layer 28, 28 ' or upper layer 29, 29 'has changed between two cycles. Accordingly, it controls the speed of the drive 10 in the way that the lower or upper layer remain constant. In this way, the intermittent is implemented Movement of the supplied residual grid 9 in a constant continuous transport speed of the remaining grid 9, with it from the feed rollers 26, 27 in the slot 8 is pushed.
  • a constant feed step between two Cutting means a constant cutting width for everyone Cut.
  • the speed of the rotor 1 is in the ratio chosen for the speed of the feed rollers 26, 27 so that at an average number of cycles of the thermoforming machine and one medium feed, for example, a cutting width of 6 mm arises.
  • this cutting width changes, if the number of cycles or the feed of the thermoforming machine change because then the speed of the feed rollers 26, 27 is changed accordingly. It then fluctuates, for example between 4 and 8 mm, but does not reach one critical width between 0 and 3 mm.
  • a loop 30 is also possible in the manner that instead of the rocker 16 a linearly movable dancer roller is arranged.
  • the position of the loop 30 could by scanning the position of the dancer roll z. B. over a linear transducers.
  • - swing arm or dancer roller - are other detection systems for that Loop 30 conceivable, e.g. B. on inductive or capacitive Way or via ultrasonic sensors.
  • a further development of the method consists in the starting speed to find the drive 10, in which the control process the position of the rocker 16 to be started, for. B. after converting the thermoforming machine or after Pause or malfunction of the thermoforming machine. It is proposed at the start of the cutting mill - swing arm 16 is standing below - to measure the time between two bars in which the Time T between two maxima or minima is determined. The rash A is also determined, due to the Rotation of the rocker 16 at a predetermined and thus known speed of the feed rollers 26, 27 at this first step.
  • the controller 23 can use these three values (Time T, deflection A, speed of the feed rollers 25, 26) after one cycle a fairly accurate speed for the feed rollers Calculate 26, 27 and specify this value. From The change is made from this speed determined in this way this speed due to a possible change in lower or upper rocker position 28, 29.
  • thermoforming machine causes an increase the rocker 16 in the upper position 29 and beyond.
  • the sensor 22 detects any angular position, the The cutting mill is switched off when the swing arm 16 a max. has reached permissible position, e.g. B. if that Residual grid 9 between the deflection rollers 12, 13 almost one Stretch position has reached.
